Benefits of technology

[0006]In one exemplary embodiment of the invention, an electronic package apparatus includes a package frame and an IC (integrated circuit) chip mounted to the package frame. The IC chip has an antenna feed network formed on an active surface thereof. A dielectric resonator antenna is stacked on the active surface of the antenna and aligned to a portion of the feed network. In one embodiment, the dielectric resonator antenna is formed by an injection molding process and is embedded within a dielectric encapsulant material having characteristics (low loss, low dielectric constant) that enhance antenna performance while servings as a package cover.

Problems solved by technology

For example, radio communication systems are typically built using expensive and bulky wave guides and / or package-level or board-level micro strip structures that provide electrical connections between semiconductor chips (RF integrated circuits) and between semiconductor chips and transmitter or receiver antennas.
As the operating frequency increases, the manufacture and assembly of conventional waveguide front-ends become more difficult.
